Android does support TTF and OTF files.

Don’t use the local hack for ie

If you realy want to support ie,use code below

<link rel="stylesheet" type="text/css" href="/css/fonts.css" />
<!--[if IE]>
    <link rel="stylesheet" href="/css/styleiefonts.css" type="text/css" charset="utf-8" />
<![endif]-->
